My friend is clever and very normal in talking today also ,  but over a period of 15 years we are noticing , he can't stick to any job , business he made loss . He blames several people for his condition. Also he blames few  people who help him . if he is angry on them he was found murmuring abusive words even while watching TV. He is always giving excuses for not doing job .He has severe anger problem , very poor in decision making and gets abusive and occasionally violent. Since 5 to 6 years he keeps saying that he wants to die . He cant do job. We feel he can't work under anyone. Once a doctor recommended tranquilizer to him but he left after 6 mths and suffered with withdrawal symptoms. Now he refuses to show to any doctor. Can these be symptoms of any psychotic disorder? He doesn't hv any hallucinations or delusion .He doesn't listen to anyone on family but expects his parents to listen to him or else he throws tantrums.Pl share your opinion as  can this can be psychotic symptom
